FASTENER FOR THE MEETING-RAILS OF SASHE'S.

SPECIFICATION formingpart of Letters Patent No. 270,993, dated January23, 1883.

Application filed September 15, 1882. (No model.)

'sash-fasteners in which the outer end of the sweep is provided withlaterally projecting shoulders, is hinged to the main portion of thesweep, and when brought to the front falls into a notch in a verticalflange, so that the shoultiers of the hinged sweep bear upon the frontof the flange by the sides of the notch therein and enable the sashes tobe drawn together by depressing the outer end of the hinged sweep. Sucha sash-fastener is represented in the accompanying drawings, in which--Figure l is a plan view thereof, and Fig. 2 a side elevation of thesame.

The sweep A is pivoted to the plate B on a vertical axis in any ordinarymanner. The keeper-plate C is provided with a vertical flange, .a, whichI' prefer to make the highest in the middle and inclined graduallytoward each end. Said flange is also provided with a notch large enoughto receive the neck of the outer end or handle, 1;, of the sweep. Saidouter end or handle, b, is hinged to the body of the sweep by pintle c.The outer end or handle, b, has two laterally-projecting shoulders, dd,for engagement with the front side of the vertical I flange a, whichflange is slightly beveled off or and the sweep is swung around to theright,

when a slight projection on the under side of b will fall into the notchf and hold the sweep in that position. If the sweep is free to beswungin either direction, a like notch for the same purpose may also beformed in the other end of the plate B.

In order to lock the sash, the outer end or handle, I), is raised alittle, then swung around over the keeper, where it will ride up theincline of the vertical flange a, and when over the notch therein itwill drop into said notch. By depressing the'onter end or handle, b, theshoulders dd bear upon the front face of the flange, and act to draw themeeting-rails of the sashes firmly together and to hold them .untilreleased, in the manner hereinbefore described.

Ordinarily sash-fasteners having a cam for drawing the meeting-rails ofthe sashes together are operated by swinging the sweep horizontally tobring it-into positiou,and sometimes the cam binds the'sweep so hardthatit is either impossible or inconvenient toswing the sweep aroundinto position for locking. In

my device the sweep is free to be brought into the position for locking,and the binding or drawing of the rails together is all done after thesweep is in position.

I am aware that a hinged sweep whose outer end rests in a notch in thekeeper,butwithout the binding arrnngement,isold in sash-fasteners, and Ihereby disclaim the same.

I claim as my invention- The combination of the keeper having thenotched vertical flange inclined on its outer face, the sweep havinghinged outer end, with projecting shoulders for engaging the inclined
